Thisinvention relates to.` a bearing assembly and .is particularly .intended rfor `.the `mounting of bearings, vsuch as ball bearings, rolleribearingsV and the like. v f

It iswell known -thatin parts; such as -wheels for roller skates. the' wheels become worn andv uselesslong beforei'fthe bearing is` affected byw the; use which has renderedtheuwheel useless Therefore, itV is yparticularlydesirable. to:V permit re-use ofthe bearing bynrendering iteasily detachable from the Wornwheelisoithat it maybe re-used in-a new wheel. Also, whereithe mounting,` in which the bearing is used is'of. particular `value, it is also desirable .tourendeiftheIbearingY itself replaceable so that thefmounting-aimay be salvagedf f The primary.` object of the invention is tofpr'ol vide yan assembly vin whichabearingl rnayfbe` detachably mountedin a member.l f, l Y

A further Objectis to provide a'novel bearingy assembly -whichiis .especiallyl adaptedvior I use in wheels fortroller skates, or `the like. and which `openingandn-is provided vwith an enlarged pore tion 9 formingl ashoulder, l0 which labuts the shoulder 1in the opening. Y, The said housing has a reduced portionfifl which 'extends through the reducedportionaoftheopening 6 and which is preferablyaflared as at. I2 tovsecure it Viirmly withbearing element |3,'-whichmary be auball bearing or the like, isfslidably mounted within the 4enlarged iportion. 9- of,` Ithe housing wand positioned against the inner surfacel of the shoulderail). x"Ihel saidbearing is `clamped irl-said positionr lby means of 4aclampingplate lli. which iswthrea'ded to .'thednner `.surface of the enlarged portion 9. The said clamping plate is preferably providedvvith an annular `shoulder VI5 which abuts thefouter ringof the.V bearing to clamp it against the innersurfaceof the shoulder iii in the housing.y As a means for locking the said clamping plate in clamping position, the same is preferably slit at one side thereof and provided witha ithreadedrecess having ataperedclamp- I ing screw |61 mounted therein. The said clampwill permit the removalof a frictionlessbearng so that the same maybefsalvaged and `used ini a new wheelywhen thel originalwheel` has be# comefuseless through wear.' 1

Further `objects ofthis invention will lbemore clearlyunderstood from .the-following description and xfrom 1 the `accompanying` drawing iinwhich: i f

Fig. `'7 .is a view similar'to 2 lbut"-showingl an axle such as usedinV the wheel. mounted to rollerskates.` i 1 As shown inl thedrawing; the numeral 5 de,

notes aV member,isuch as aroller skate 'wheelhin which a bearing assemblyl comprising my in-1- vention is mounted. .The said member is preferably providedwith an opening 6 extending therethrough and having an intermediate shoulder Vl. A bearing housing 8 is located within the said `side view of a roller :skate Wheel com.y taining my improved .bearingassemblyz:

ing platedsalso provided'with tool receiving apertures i1 whereby itl may :be turned to its clamping position. 1u

.When thevsaidvplateuhas been turned in positionfto .securelyV clamp the vouter ring of the *bearing between the annular shoulder i5 and the shculderel; the i said. screw I6 may be turned I '-tcy expandathesaid clamping plate `against the inner threadedsurface infithe'portion 9 and thereby lock 'the plate insbearingfclamping position.`

v,Fromthe above description, it will be readily understood that when .'afwheel or member, in

*plate Elis provided with extensions 2| which arereoeivedlin` the'fsaidfnotches and maybe turned to t int"y the'extensionsrl to thereby secur'esaid clampingplate in position. The said vplate 2S is also' provided with clampingscreW-s 22 which m'aybe forced 'against the outer ring of the bearingrnemben'as clearlyillustrated in liiigxlijto clamp said ringagains-t the inner surface of .the shoulder lll-a.

v It will be noted that the bearing member is clamped in such a manner that the outer ring, or raceway, is securely and rigidly held in position against the shoulder in the housing while the inner ring, or raceway, is free to rotate.

As illustrated in Fig. '7, the said bearing assembly may be mounted to an axle 23, or similar member, by securing the inner ring of the bearing thereto with a nut `24 which will secure the inner ring against a shoulder 25 that may be provided by a positioning sleeve 26 as commonly used in roller skate construction. When so mounted, the inner ring is held stationary on the axle while the entire bearing assembly is permitted to rotate thereon.

The plate 20 may be provided with openings 2li-a to receive a wrench, or other suitable tool, for turning said plate when assembling it to the housing 9- a.

From the above description it will be clearly understood that my invention provides a bearing assembly in which a member supporting, or supported by, a frictionless bearing, is provided with a shoulder against which a housing may be securely positioned and the said housing is provided with means for detachably mounting -the bearing therein and in such a manner that the said bearing may be readily removed for re-use while the worn part may be discarded,

My invention is also valuable wherein a frictionless bearing is mounted in an important or expensive member of a machine and wherein it may be desirable tohave the bearing readily re placeable with a new one to thereby salvage the more expensive member.

It will therefore be understood that, by my invention, I have provided a simple and inexpensive bearing assembly which will render a bearing member quickly and easily detachable or interchangeable.

I claim:

l. In combination with a member comprising a bearing; said member having an opening extending therethrough with an enlarged portion forming an internal shoulder in said opening and a reduced portion extending from said shoulder to the opposite side of said member, a tubular housing mounted within said member and having a wall of substantially uniform thickness, a shoulder on said housing abutting the internal shoulder in said opening, a reduced portion in said housing extending through the reduced portion of said opening, the end of said reduced portion of the housing being flared outwardly and seated against the bottom of a recess in surrounding said opening for securing said housing in said member with the shoulder thereon in abutment with the internal shoulder in said opening, a bearing detachably mounted in said housing, and means for securing said bearing therein.
